Microsoft Certified: Azure AI Fundamentals (AI-901) Practice Tests

Validates foundational knowledge of AI concepts, responsible AI and building generative AI, vision and speech solutions.

AI-901 runs 45 minutes, and Microsoft says most of its exams have 40 to 60 questions. It mixes AI concepts with Microsoft Foundry tasks and Python SDK snippets. We compared the main options on question volume, timed sets and price.

Most people should start with Microsoft's free practice assessment, then add a low-cost bank for extra volume. The exam is new, so paid sets are still young.

Free first look

AI-901 practice assessment

Microsoft's official AI-901 practice questions, now hosted on AI Skills Navigator rather than Learn. The best place to see how concept and Foundry questions are worded.

Great fit if you want a free official check before or after the learning paths.

Poor fit if you need a large bank or several timed full runs; add Tutorials Dojo or the Udemy set.

Low-cost timed sets

AI-901 Azure AI Fundamentals Practice Exams

Timed, review, section-based and randomized modes written for the two AI-901 skill areas, with explanations that link to Microsoft documentation.

Great fit if you want low-cost timed practice written for AI-901 rather than the retired AI-900.

Poor fit if you want many full runs; at this size, add the Udemy set from Joel Palmer.

Largest question pool

AI-901 Practice Tests 2026: Microsoft Azure AI Fundamentals

Six full tests of 55 to 67 questions each, with explanations, covering responsible AI, Foundry, speech, vision and information extraction. The best-rated of the 2026 Udemy sets.

Great fit if you want enough volume for several full runs across both skill areas.

Poor fit if you want Microsoft's own wording; use it alongside the free official assessment.

What to look for in a AI-901 practice test

  • Written for AI-901, not the retired AI-900. AI-901 replaced AI-900 with skills measured as of April 15, 2026: AI concepts and responsible AI (40 to 45%) and implementing solutions in Microsoft Foundry (55 to 60%). An AI-900 bank under-tests Foundry and code.
  • Foundry and Python snippet questions. Candidates report roughly a third of the exam on Foundry and Python: client setup, authentication and response handling in short SDK snippets. Look for a bank that includes code and portal questions, not only definitions.
  • Responsible AI and workload questions. Passing candidates describe about ten questions on responsible AI principles plus speech, vision and information-extraction questions. Make sure a bank covers all of the Foundry areas, including Content Understanding.
  • Enough questions for a few timed runs. The exam is 40 to 60 questions in 45 minutes. Tutorials Dojo has 60+ questions and the largest Udemy set about 380, so decide between a quick check and several full runs.
  • Skip sites selling "real exam questions." Sites promising actual AI-901 questions or a guaranteed pass are selling leaked or copied items. Microsoft's exam policies count brain dumps as cheating and let Microsoft revoke your certifications and bar you from future exams. A real practice test explains why each answer is right; a dump only lists answers.

How to use AI-901 practice tests

  • Take the official assessment after the learning paths. Use Microsoft's free assessment once you have worked through the two Learn paths, to see which of the two skill areas needs another pass.
  • Do the Foundry exercises, then read the code. Build the Learn exercises in your own subscription and read each snippet line by line. Candidates found the last stretch of the exam, heavy on Python and SDK code, the trickiest.
  • Review every explanation, including right answers. Candidates describe the exam as testing whether you understand concepts rather than recall definitions, so know why each wrong option fails.
  • Finish with a timed run. Run one full set against the 45-minute clock close to your exam date, then spend the time you have left on your weakest skill area.

AI-901 practice test FAQ

Is there a free AI-901 practice test?

Yes. Microsoft's official practice assessment is free on AI Skills Navigator with a sign-in. John Savill's one-hour AI-901 cram on YouTube is a free review, though it is a video rather than a question set.

Is AI-901 the same as AI-900?

No. AI-901 replaced AI-900 and goes deeper into Microsoft Foundry, with Python SDK snippets, so AI-900 practice tests do not fully prepare you.

Is AI-901 hard?

Candidates call it a basic certification, with the first part straightforward and the Python and SDK questions at the end trickier. One passer described it as half easy and half tricky.

How many AI-901 practice tests should I take?

The official assessment plus two or three full timed sets is enough for most people. Review every explanation before taking another set.
